Apoptosis – programmed cell death

“Apoptosis is a process where a cell is degraded in order for it to be ultimately engulfed and recycled. Apoptosis can occur when a cell has become mutated and is on the verge of becoming a cancer. Apoptosis is also the reason why we don’t have webbed hands and feet. What basically happens is that the killer “t” cell communicates with the diseased cell by adhering to it by binding its death ligand to the death receptor on the diseased cell. This causes adapter proteins to attach to the cytosolic side of the receptor. This leads to a signal cascade which involves the recruitment of various other proteins and ultimately results in the death of the cell.” ~ bowlerdude on YouTube.

Key knowledge:

  • Understand the extent of the plasma membrane in forming a series of membraneous channels for the packaging and transport of biomolecules throughout eukaryotic cells.
  • Enhance knowledge and understanding of the structure and function of cell organelles.
  • Distinguish the different ways in which biomolecules enter or leave cells.
  • Develop knowledge and understanding of connections between cells.
  • Extend understanding of apoptosis.

Possible Tasks:

  1. Create a “Thinglink” interactive image, labelling the different parts of a eukaryotic cell.  
  2. Create a database of terms and definitions on Quizlet. 
  3. Decorate a cake to show the different organelles of a plant or animal cell. Label with toothpick flags.
  4. Create a video describing the different forms of active transport using “common craft” style or 3D animation.
  5. Create a labelled model of the “phospholipid bilayer with integral and peripheral proteins”.
